Some people are afraid of trouble or do not want to buy a bean grinder, usually at home to buy coffee has been ground ready-made coffee powder, then pay special attention to the storage problem, because Taiwan's humid climate, coffee powder after opening is best not placed at room temperature, more appropriate way is placed in a sealed jar into the refrigerator, and do not and garlic, fish and shrimp and other heavy taste of food with the same place. Because coffee powder is easy to absorb flavor, a careless coffee becomes a strange taste, so even the best quality coffee is ruined. Some people put ground coffee in the refrigerator as deodorant, which is a good way to make the best use of it.

Coffee beans, those dark brown beans seem ordinary, but there are a lot of knowledge at all stages. For a coffee cook and drinker, a general understanding of coffee bean cultivation, production, roasting and other professional knowledge is enough, and the production of things can be handed over to coffee merchants. After all, this is an era of division of labor. But grinding coffee is the responsibility of the user, and it must be understood exactly.

When grinding the beans, the thickness of the powder depends on how it is cooked. The shorter the cooking time, the finer the ground powder; the longer the cooking time, the coarser the ground powder. In terms of actual cooking, ESPRESSO machines take a very short time to make coffee, so the ground coffee powder is the finest, and the coffee powder is as fine as flour; it takes about one minute to cook coffee in the "plug wind" way, and the coffee powder is a medium coarse grind; American filtered coffee takes a long time to make, so the coffee powder is the coarsest, one by one like the Beijing grain on the shell beach. Grinding coffee powder of appropriate thickness is very important for making a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine, and cooked for a long time, resulting in excessive extraction, coffee may be very bitter and lose aroma; on the other hand, if the powder is very coarse and cooked too fast, resulting in insufficient extraction, then coffee will be tasteless, because there is no time to dissolve the water-soluble substances in the powder.

Coffee grinders come in a variety of brands and models, but ideally one that can adjust the size of the ground beans. When grinding with a bean grinder, do not grind too much at a time, enough powder for one use is good, because the longer the bean grinder is used, the easier it is to generate heat, which indirectly causes the coffee beans to be heated in the grinding process and causes the aroma to be released in advance, which will affect the aroma of the cooked coffee.
